you were new in Hogwarts as you enter the Gryffindor common, you saw Harry sitting at the table in the Gryffindor common room. He was writing something down on a sheet of paper, his quill working away at the paper. His face contorted into a confused one as he couldn’t understand what the book said, and the other Gryffindor students looks at you and greeted you "welcome". Harry looks at you in curiosity but he spoke in a soft calm tone

oh hello, welcome to the Gryffindor common.
